EXPLOSIVE PEOJECTILE.

Specicaton of Letters Patent.

Patented Dec. 5, 1916.

Application led May 20, 1916. Serial No. 98,771.

T0 all whom t may concern:

Be it known that I, ERNESTO Riccio, a subject of Victor Emmanuel III,King of Italy, whose residence is No. 2409 Beaumont avenue, borough andcounty of the Bronx, city and State of New York, have invented a new anduseful Explosive Projectile; and the objects of my improvement are toprovide an exceedingly simple shell which may be made of brass or steeland in which may be used any explosive composition of chemicalsubstances and the eHicacy of which is certain and inevitable. I attainthese objects by the mechanism illustrated in the accompanying drawing,in which- Figure l is a View of a projectile in accordance with myinvention, partly in side elevation and partly in longitudinal section.

Fig. 2 is an enlarged sectional View of the percussion disk, showingalso the firing pin in side elevation and partly broken away.

The projectile comprises the charge containing shell A and the piercingcap end B, connected .together as by threading or in other suitablemanner.

The cap B has an axial opening C through which extends the shank of thetiring pin D of a length to have its outer end project beyond the tip ofthe cap B and having a conical inner end D, the shoulder between theconical head D and shank preventing the pin from dropping out of thecap.

Seated on the outer end of the threaded extension A of the shell A andheld by the cap B is a disk E provided with a central opening E filledwith potassium chlorate and antimony or other readily combustiblesubstance E capable of igniting the charge F in the shell A whensubjected to concus- Gopies of this patent may be obtained for sion. Thepercussion charge F is held in the kaperture in the disk by layers ofpaper, cloth or other readily puncturable material G pasted or otherwisesecured to the side faces of the disk. The covering G on the outer faceof the disk holds the cone-head of the iiring pin out of Contact withthe percussion charge in the disk until such time as the pin is forciblydriven inwardly of the projectile.

In operation, the projectile being fired and the extending end of thepin coming in contact with an obj ect, it is driven inwardly, and theconical head of the pin pierces the covering of the disk, `exploding thepercussion charge and exploding the charge of dynamite, powder or othercharge in the shell.

What I claim is:

A projectile comprising a shell containing an explosive charge, a capdetachably secured thereto and having an axial opening, a disk heldbetween the cap and shell and having a central opening alining with theaxial opening in the cap, said opening in the disk having a filling ofexploding material, a covering of readily pierceable material on thefaces of said disk for retaining the charge therein, and a firing pinslidably fitted in the axial opening of the cap with its outer endextending beyond the cap and having a conical head on its inner end forpiercing the disk covering when the pin is driven inward and for holdingthe pin against outward movement.
